The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

Cement Grinding: cement grinding is the final stage in Portland cement manufacturing. In this step, clinker will be ground in grinding mill to reach the qualified fineness of cement product. During the grinding, we usually add gypsum, fly ash and other raw materials into the cement to realize the different usage of cement.

Materials ground Portland clinker is the main constituent of most cements. In Portland cement, a little calcium sulfate (typically 310%) is added in order to retard the hydration of tricalcium aluminate. The calcium sulfate may consist of natural gypsum, anhydrite, or synthetic wastes such as fluegas desulfurization gypsum.
